Guest JDMDOM Posted August 17, 2009 Share Posted August 17, 2009 I'm looking to upgrade my fule delivery system to a double pump, fuel rail, regulator and injectors looking to get 650-750 injectors. the question is what is low impedance and high impedance? and what is the diference? wich one is better for a 650whp Quote Link to comment Share on other sites More sharing options...
dude Posted August 17, 2009 Share Posted August 17, 2009 either will do dude you just need to change the resistor pack accordingly, if you have a J spec and got hold of a set of low impedence injectors for a UK/US then it would be worth getting a resistor pack from Heckler, if your buying new you may as well get the correct impedence.

paul mac Posted August 17, 2009 Share Posted August 17, 2009 I'm looking to upgrade my fule delivery system to a double pump, fuel rail, regulator and injectors looking to get 650-750 injectors. the question is what is low impedance and high impedance? and what is the diference? wich one is better for a 650whp there are two types of injector we are talking about here, peak and hold (low impedance) and saturated (high impedance), both have advantages and disadvantages the principle difference being the way they are switched. At the size of injector and the power level you want i would go for peak and hold every time, they react quicker, you will be able to run them direct from your aftermarket ecu (no resistor pack), and saturated injectors dont usually cater for these larger sizes (for a good reason) that you will need Quote Link to comment Share on other sites More sharing options...
Guest JDMDOM Posted August 24, 2009 Share Posted August 24, 2009 So hight impandance will be good for about 650whp with out a resistor pack, i have a HKS Fcon V for the ignition/timing and fuel will that be enough along with the fule rail, doulbe or triple pump and regulator? sorry i'm fairly new to the supra scene Quote Link to comment Share on other sites More sharing options...

Guest JDMDOM Posted August 25, 2009 Share Posted August 25, 2009 Actually is a Fcon V from jp is not the pro, i been looking online to get specs and i can't find it anywere!! if you know anything about the Fcon V please let me know, i don't if is tuneable, since online the only thing i found was the pics. but what type of removal kit eare you talking about?
